9217 :: 'import os' not used. Wrong Error Message

• Clavismax (orginal) [2022-06-08T08:40:08+02:00] view original

  This code only works fine with the import statement:

  import os
  
  when not (declared(commandLineParams)): # POSIX available?
      echo("Your System ist not POSIX-Compatible.",
          "Your Parameters cannot be determined because the required",
          "Function is not available (commandLineParams).")
  else: # Found POSIX!
      echo("bla bla")
  Run

  But VSCode marks 'os' as import not used... but it is used!

  Is this a nim or a VSCode bug? and how can i fix it? (or work around: turn off this message!?)

  its not really used. if you remove the os import, you still have a valid program. you are just checking if symbol is available, you are not requiring it.

  mark import as {.used.}.

  Thank you, that helps me.

  By the way, commandLineParams is defined for both Windows and Posix-esque targets. So checking if it is declared wouldn't really check if you're on a Posix-compatible machine or not. I think you might be looking for when defined(posix).
